If I ever have a pool I'm totally going to get these! The Ocean Art Light-up Jellies from Swim Ways are eerily life-sized jellyfish decorations for swimming pools. Each light-up jellyfish has LEDs inside and glow as they float across the pool.
Set of 3 Floating LED Pool Speakers. Simply toss the waterproof speakers into the pool and start the music, transmits wirelessly via from a single bass station. When not in the pool, the speaker work equally well on dry ground.
